Updated September 3, 2026. Quick answer: Kentucky Employees Retirement System (KERS): the COLA is discretionary, and by statute only the General Assembly, not the KPPA or governing boards, can grant one, service credit can be purchased, and no DROP was found. Vesting takes 60 months of service credit under age 65 (48 months at 65 or older) for Tiers 1 and 2; Tier 3’s cash-balance plan vests at a flat 60 months.

The verdicts
| Is the COLA granted? | Discretionary (General Assembly holds sole authority) |
|---|---|
| Is the COLA compounded? | Not stated |
| Vesting | 60 months (48 if age 65+) for Tiers 1&2; 60 months for Tier 3 |
| Buy service credit? | Yes |
| DROP? | None found |
| State | Kentucky |
Those first two rows are separate questions and are routinely confused. Whether you get an increase at all is one thing; whether it compounds is another. A system can grant an increase automatically every year and still compute it against your original benefit forever, which is a materially worse deal than it sounds.
The COLA
“COLAs will only be granted if the CERS and KRS Boards determine that assets of the systems are greater than 100% of the actuarial liabilities and legislation authorizes the use of surplus funds for the COLA; or the General Assembly fully prefunds the COLA or directs the payment of funds in the year the COLA is provided… the Kentucky General Assembly (and not the CERS or KRS Boards, the KPPA, or the Governor) actually holds the authority to grant COLAs under Kentucky Revised Statutes 61.691 and 78.5518.” A separate, unrelated benefit (a 1.5% cumulative increase to the retiree health-insurance dollar contribution, not the pension check) should not be confused with this pension COLA.
Coordinate this with your overall retirement plan
An adviser can help weigh a COLA that may not compound, a service-credit purchase that may never pay for itself, or a DROP election against the rest of your retirement plan, but that does not replace the numbers in your own member statement.

What happens when you press the button
It requests contact details and phone verification by text. Nothing loads and nothing reaches Kapitalwise until you press the button. Submitting the form does not guarantee an adviser or a match. This matching form is not tax or legal advice.
Buying service credit
KERS offers more than 30 purchase types under Tier 1 alone, including recontribution of refunded service, active-duty and National Guard/Reserve military service, delayed/past service, up to 10 years out-of-state service, up to 5 years non-qualified service (with 15 years total service required), omitted service, summer months for school employees, and sick-leave conversion. Cost formula: “Higher of Current Rate of Pay / Final Rate of Pay / Final Compensation * Actuarial Factor * Years Purchased”, with the actuarial factor varying by age, accrued credit, benefit factor and final compensation. Refunded-service repayment costs “the amount of contributions withdrawn plus interest calculated from the time of withdrawal.”
Run your own numbers before deciding: some purchases never recover their cost, and the calculator shows which.
Vesting
“In order to be vested, a member under the age of 65 must have at least 60 months of service credit in the systems operated by KPPA while a member over the age of 65 must have at least 48 months of service credit in the systems operated by KPPA.” Tier 3 (cash balance): “Once a member obtains 60 months of service credit, the member is considered vested”: no age-based reduction found for Tier 3.
DROP
No mention of “DROP” or “Deferred Retirement Option” appears in the Summary Plan Description, Tier 1 Guide, or Tier 3 Guide.
DROP is rarer than it appears across the systems on this site: most have none.
Payment options and the survivor election
KPPA, the Kentucky Public Pensions Authority, runs KERS, and a retiring member picks a payment option from a menu. The Your Payment Options page begins with a structural point: “All monthly payment options offered are lifetime benefits to the retiree.” It also limits who can be named: “At the time of retirement, the member may name only one person, his or her estate, or a trust as beneficiary of the monthly retirement allowance.”
The choice is close to permanent. The Summary Plan Description says “a retired member may not change their payment option or account beneficiary designation except in limited circumstances” and points to Kentucky Revised Statute 61.542. As the SPD summarizes that statute, a retiree on the Basic, Annuity, Life with 10, 15 or 20 Years Certain options, or the Social Security Adjustment Option without Survivor Rights, may change the beneficiary at any time, and “Within 120 days of marriage or remarriage, a retired member may change their beneficiary to their new spouse and elect a survivorship payment option.”
The survivor options each state what the beneficiary receives. Under Survivorship 100%, “If the member passes away before the beneficiary, the beneficiary is eligible for the same monthly benefit until death.” Under Survivorship 50% the beneficiary gets half of the member’s monthly benefit, and under Survivorship 66 2/3% the SPD says “the beneficiary is eligible for a monthly benefit equal to 66 2/3% of the member’s monthly benefit until death”. The Pop-Up option pays the beneficiary the same monthly benefit, and the SPD adds that if the beneficiary dies first the member’s benefit rises to the Basic amount. It also says “The member’s benefit will also Pop-Up if the member’s beneficiary is a spouse and they become divorced.”
The period-certain options work differently. Life with 10 Years Certain is open to members under age 76, Life with 15 Years Certain to members under age 68, and Life with 20 Years Certain to members under age 62, per the payment options page. For the 10-year version, the SPD says “If the member dies before 120 payments have been made, the beneficiary will receive the remaining payments.” After that the payments to the beneficiary stop. The Basic/Annuity option gives the beneficiary nothing monthly, and the SPD says “It provides the highest monthly lifetime benefit.”
Two conditions can narrow the menu. Spouses get flexibility: “If the beneficiary is the member’s spouse, the age requirements are waived”. For anyone else, “IRS regulations require that KPPA perform a test to determine eligibility for certain payment options based on the age difference between a member and a non-spouse beneficiary.” Health coverage is the other catch: “for most payment options, an individual must be receiving a monthly retirement payment to enroll in health insurance”. For the survivor-versus-single-life tradeoff in general, see single life versus joint and survivor pension.
| Option | Member monthly | Beneficiary monthly |
|---|---|---|
| Basic/Annuity | $1,452.33 | $0.00 |
| Survivorship 100% | $1,272.52 | $1,272.52 |
| Survivorship 66 2/3% | $1,326.95 | $884.68 |
| Survivorship 50% | $1,356.08 | $678.04 |
| Pop-Up Option | $1,264.99 or Basic | $1,264.99 |
A computed example from the SPD’s sample member, not a KERS formula: the Basic/Annuity payment of $1,452.33 less the Survivorship 100% payment of $1,272.52 is a computed $179.81 per month, which is a computed 12.4% lower than Basic. The SPD is a KPPA document that covers more than one system and its sample member works for a county (CERS) employer, so this shows the size of one sample trade-off and not what a KERS member would see.
What the pages read do not state: the actuarial factors behind the reductions, the sample member’s ages, or a written spousal consent requirement (the word consent does not appear in either document). The Self Service estimator is where the SPD points members to run their own beneficiary scenarios.

Taking a refund of the account balance
The SPD gives members who leave employment a three-way choice: “Upon termination of employment, a member has three options in regard to their retirement account”. The options are to retire if eligible, leave the contributions in the account until eligible, or take a refund.
What comes back is limited to the member’s own money. The SPD says “they will receive their individual retirement contributions plus any accumulated interest”. It lists the exclusions by tier: “Tier 1 members will not receive a refund of any employer contributions.” Tier 2 members also do not get back employee contributions to the Insurance Fund, and the SPD notes “the one percent health insurance contribution paid by Tier 2 and Tier 3 members is deposited in a non-refundable trust to fund insurance benefits”.
Tier 3 depends on vesting. The SPD says “Tier 3 members with less than 60 months of service credit are eligible for a refund of the member portion of the account balance.” A Tier 3 member with at least 60 months is vested and receives employer pay credits and any associated upside sharing interest.
The money can go two places. The SPD says “Refunds can be paid directly to the member” or the funds can be rolled into another qualified retirement plan or an IRA, as the SPD puts it. On a direct payment, “KPPA is required to withhold 20% for federal income taxes”, and the SPD adds “The amount withheld is not a penalty tax”. It also warns that additional taxes due to age or other factors may apply. For the general version of that rule, see the 20 percent withholding rule on a pension lump sum.
The cost of a refund goes beyond the tax withholding. A sidebar in the SPD states “By taking a refund, members forfeit eligibility for future benefits including health insurance and the $5,000 death benefit.” That is the point to weigh against leaving the account in place, a comparison covered more generally at pension refund versus leaving it.
Process and later return to work are also set out. The form is “Form 4525, Application for Refund of Member Contributions and Direct Rollover/Direct Payment Selection”, and “A refund cannot be processed until at least 45 days following the termination date” once the member and employer have supplied everything. If a member returns to the same system within 45 days, “the member will become ineligible to receive the refund and will be required to pay back the refund if payment has been issued”. After that window, the SPD says a member who comes back to a participating employer may be able to purchase the refunded service, but “The purchase will not reestablish the member’s original participation date which determines the benefit tier they are in.”
| Item | Figure | Where the SPD states it |
|---|---|---|
| Federal withholding on a direct payment | 20% | SPD, Refund of Account Balance |
| Wait before a refund can be processed | 45 days | SPD, Refund of Account Balance |
| Return to work that voids the refund | 45 days | SPD, Subsequent Employment |
| Death benefit forfeited | $5,000 | SPD, Refund of Account Balance |
| Tier 3 vesting for employer pay credits | 60 months | SPD, Refund Payments |
| Tier 3 annual interest on accounts | 4% | SPD, Interest on Accounts |
| Tier 2 interest rate on accounts | 2.5% | SPD, Interest on Accounts |
What the pages read do not state: a dollar example of a refund, or how interest is applied to a balance paid out mid-year. The SPD gives interest rates by tier (2.5% for Tier 2 and 4% for Tier 3 are in the table above), but it also says interest is calculated from the balance as of June 30, so no computed refund example is shown here. The refund amount comes from the member’s own Annual Statement and KPPA.

Partial lump sum and actuarial lump sum options
KERS has two separate lump-sum routes at retirement, and the names are easy to blur. The newer one is the Partial Lump Sum Option, or PLSO. The payment options page says it is “Available to members effective January 1, 2024” and describes it as “a one-time payment equal to 12, 24, 36, 48, or 60 times the monthly benefit under the Basic or Annuity payment option, plus a monthly payment to the retired member until death”.
The trade is a smaller check for life. KPPA says “The monthly payment is actuarially reduced to reflect the lump-sum payment amount.” The page also says “This lump-sum is paid separately by check and mailed”, while the monthly payment is direct deposit. The Summary Plan Description, by its own cover, was “Revised December 2022”, before the PLSO start date, and the payment options section of that PDF does not mention it.
There are two versions. The version without survivor rights bases the lump sum on the Basic or Annuity option, and KPPA says “This option does not provide any benefits to the beneficiary after the member’s death.” The page adds that a beneficiary can still receive any remaining account balance. The version with survivor rights bases the lump sum on the Survivorship 100% option, and KPPA says “If the member dies before the beneficiary, the beneficiary is eligible for the same monthly benefit.”
A computed example from an assumed $2,000 monthly Basic benefit, not a KERS figure: the lump sum is a multiple of that monthly amount, so 12 times $2,000 is a computed $24,000, 36 times $2,000 is a computed $72,000, and 60 times $2,000 is a computed $120,000. The reduced monthly payment that goes with each choice cannot be computed from the pages read.
The older lump-sum route is different and carries heavier consequences. The Actuarial Lump Sum Refund is, in the SPD’s words, “the actuarial equivalent of the amount the member would have received had the benefits been paid over 60 months”. Taking it means “the member forfeits all other benefits, including health insurance benefits and the $5,000 death benefit”. The SPD adds “This is a retirement benefit, not a refund of the account.” and “An individual electing this payment option cannot repay the actuarial refund if employed with a participating employer at a later date.” Tier 3 is excluded: “Tier 3 members are not eligible for the Actuarial Refund”.
The SPD sample member, a county (CERS) employee, shows the scale. Sixty payments of the sample Basic amount of $1,452.33 come to a computed $87,139.80, against a printed actuarial lump sum refund of approximately $72,564.07. The pages read do not state the discount rate or factors, so the gap should not be read as a rule.
| Item | Figure | Where KPPA states it |
|---|---|---|
| PLSO lump sum multiples | 12, 24, 36, 48 or 60 | Your Payment Options |
| PLSO start date | January 1, 2024 | Your Payment Options |
| Actuarial lump sum period | 60 months | SPD, Payment Option Descriptions |
| Death benefit forfeited by actuarial lump sum | $5,000 | SPD, Payment Option Descriptions |
| SPD sample actuarial lump sum | $72,564.07 | SPD, Payment Option Example |
What the pages read do not state: the actuarial factors, how the PLSO monthly reduction is set, the tax treatment of a PLSO payment, or whether any tier is excluded from it. For the general comparison of lump sums and monthly income, see lump sum versus monthly annuity break-even. The KPPA retirement counselors and the member’s own estimate are where the actual numbers come from.

What could not be verified
REFUND TERMS: this page does not state what happens to your contributions if you take a refund instead of leaving your account with the system: that comparison was not independently researched for this system this session, and is left as an open gap rather than guessed from another system’s rule. Consult your own plan’s refund/forfeiture terms before deciding. Any additional field marked “not stated” in the verdicts table above was genuinely absent from the official materials read, not omitted for space.
